The invention relates to a mechanism comprising at least one spring () for compensating the weight of a closing screen, said spring () being fixed, at one of its ends (), to a ring () which is rotatably arranged around a shaft () having a circular cross-section. A stop spring () which is arranged around the shaft () ensures a one-way coupling between the ring () and the shaft (), means () being provided for controlling the centripetal effort exerted on said shaft () by the stop spring ().

Mechanism for tensioning a compensation spring for a closing or sun protection installation

A mechanism () comprising a driving element () for rotationally driving a winding shaft () for a closing or sun-protection installation of an opening () and at least one spring () for compensating a weight of the installation. The spring () is mounted around the driving element () and is jointly associated with a sub-unit (), which can be at least partially introduced in a unitary manner inside the shaft (). The spring () includes a first end () kinematically linked to said driving element () so that the first end () is immobilized in rotation abut an axis of rotation (X-X') of the shaft (), and a second end () kinematically linked to the shaft () when the sub-unit () is placed inside the shaft () so that the second end () rotates about the axis of rotation (X-X&#x2032;).
